What Are PTFE Rubber Flange Gaskets?
At Stephens Gaskets we provide PTFE rubber flange gaskets as high-performance sealing solutions designed for use between flanged joints in pipe systems.
By combining PTFE (Polytetrafluoroethylene) with rubber such as EPDM, Nitrile, or Silicone, these gaskets deliver outstanding chemical resistance, thermal stability, and sealing flexibility.
Key Features of PTFE Rubber Flange Gaskets
- Chemical Resistance: PTFE resists acids, solvents, and aggressive chemicals.
- Temperature Range: Can withstand temperatures from -200°C to +260°C depending on rubber type.
- Non-Stick Surface: Prevents product build-up and simplifies disassembly.
- Sealing Flexibility: Rubber ensures conformity to uneven or worn flange faces.
- Durability: Resists wear, creep, and chemical degradation over long service periods.
- Food-Grade & Non-Toxic: Suitable for sterile and hygienic environments (FDA, WRAS compliant options available).
Applications Across Industries
Material Options for Specific Manufacturing Requirements
| Material | Best For | Temp Range (Approx.) |
|---|---|---|
| EPDM | Water, steam, acids, alkalis | -45°C to +130°C |
| Nitrile (Buna-N) | Oil, fuels, industrial fluids | -35°C to +120°C |
| Silicone | Food, pharma, extreme temperatures | -60°C to +230°C |
| Viton® (FKM) | Solvents, high temp, chemical plant use | -20°C to +250°C |
| PTFE-Coated | High-purity, non-stick sealing | -200°C to +260°C |
Key Benefits of PTFE Rubber Flange Gaskets
1. Chemical Resistance
PTFE protects against nearly all industrial chemicals, acids, and solvents – ideal for aggressive applications.
2. Thermal Stability
Performs in both cryogenic and high-temperature environments. Maintains seal integrity under fluctuating conditions.
3. Flexible & Resilient
Rubber core absorbs vibration, accommodates thermal expansion, and ensures sealing under pressure.
4. Clean, Non-Contaminating
PTFE’s smooth surface prevents contamination and supports hygienic operations in food and pharmaceutical lines.
5. Easy Installation
Flexible and forgiving. Reduces assembly time and simplifies maintenance or replacement.
6. Long Service Life
Minimises downtime and lowers total cost of ownership in harsh or critical systems.
Solving Common Concerns
“Aren’t these gaskets expensive?”
PTFE rubber gaskets are more costly than basic rubber types, but they significantly reduce failures and downtime in corrosive or high-performance environments – delivering value over time.
“Will they creep under pressure?”
We use reinforced designs and quality PTFE bonding to minimise cold flow and extend life in static joints.
“Are they difficult to install?”
Our gaskets are precision-cut and easy to handle. We provide torque guidance to prevent over-compression or PTFE layer damage.
“Do they suit my chemicals?”
We supply chemical compatibility charts and provide expert advice to ensure the gasket matches your media.
“Are they available for urgent jobs?”
Yes – we offer fast turnaround and UK-wide shipping. Custom sizes can often be delivered within days.
